Question

how do you write 450,000 in scientific notation?

× 10

Explanation:

Step1: Move decimal point

Move the decimal - point in 450000 to the left until there is only one non - zero digit to the left of the decimal point. We get 4.5.

Step2: Count decimal places moved

We moved the decimal point 5 places to the left.

Step3: Write in scientific notation

In scientific notation, a number is written as \(a\times10^{n}\), where \(1\leq a<10\) and \(n\) is an integer. So, \(450000 = 4.5\times10^{5}\).

Answer:

\(4.5\times10^{5}\)
